Your city editor seems to downplay the significance of the actions by Barclays (Other banks in our sights over rates, says FSA, 28 June). What she describes as a record-breaking fine by the FSA is a fraction of the fine by the US authorities. The reality is that once a bank starts manipulating the Libor interest rates, that means the banking system is not just reckless but corrupt. The government’s banking proposals address none of this. They instead reiterate the concept of Chinese walls and firewalls … which are precisely what have failed.Andrew PrestonAxbridge, Somerset

• There could be no greater contrast between Barclays and other banks with Quaker roots. The founders of the Quaker banks were serious people, who invested in Britain’s industrial revolution. Short of putting Quakers back in control, it is difficult to see how these modern leviathans can now be reformed.Dave FeickertWhanganui, New Zealand
